App1ication filed November 8, 1913. Serial No. 799,957.

To all whom it may concern Be it known that l, F INGAL GUsTA'FsoN,asubject of the Kingof Sweden, residing at Cloquet, inthe county ofCarlton and State of Minnesota, have invented certainv new and usefulImprovements in Pocket- Alarms, of which the following is aspecification.

The present invention appertains to alarm devices, and particularlyv tothat type adapted for disposition in a vgarment pocket and with which anobject in said pocket cooperates in such a manner that an alarm issounded upon the removal of the object therefrom.

More specifically the object in view is the provision of an alarmsounding device suitable for connection within a pocket and carrying anoperating member normally placed under tension by an object, such as apocketbook, against which it impinges, whereby unauthorized removal ofthe pocketbook from the pocket will release the operating memberandactuate the alarm that the removal may be thereby detected.

With the above and other objects in view, this invention consists in theconstruction, combination and arrangement of parts all as hereinaftermore fullyv described, claimed and illustrated in the accompanyingdrawings, wherein: y I

Figure 1 is a vertical sectional view showing the. application of vmyvalarm device within a pocket and its coperation with apurse also in saidpocket; Fig. 2 is ay fragmentary sectional view similar tokFig. `l andshowing the position of the alarm upon removal of the object andactuation ofthe operating'y member for saidalarm, Fig. 3 is a top planview; and Fig. 4 .is a detail bottom plan of one of the parts foroperating the hammer member'of-the alarmdevice. Fig. 5 is a verticalsection taken on the planes indicated by line ',-f-of Fig.,1.

' 'Throughout the following detail descrip- ,i

tion, and on the several'gures of thedrawings, similar parts arereferred to by like reference characters. p

It isto be understood in premising the description of this inventionthat the alarm device constituting the same may be disposed i'n anypocketroffa garment and it is still further comprehended that the saiddevice may be connected with an independent pocket member that may besuitably inserted in a' garment pocket and fastened therein as aliningmember forsaid pocket.

vW'ith lthe foregoing in view the numeral l designates a garment pocketand 2 an object disposed therein such as a purse or pocketbook. Withinthe pocket l. and preferably at anupper corner of the same is suitablysecured the alarm device forming the embodiment of my invention andwhich device comprises a casing 3 of any suitable form and size withinwhich is housed the valarm mechanism to be more fully describedhereinafter. Connected to the casing eX- teriorly of the same andpreferably at its upper corner `4" is provided an operating member 4 inthe form of a spring which extends downwardly substantially the lengthof the casing 3 and has at its lower terminal an arm 4 preferably bentlaterally for a purpose which will be understood as` this descriptionproceeds. The spring member 4 is adapted to actuatey the alarm mechanismwithin `the casing 3 and `for this purpose is provided a laterallyextendingarm or eX- tension 5 projecting into said casing near its lowerextremityv asi will bemost clearly seen by'reference to Fig. 1 of thedrawing. The operating member 4 is normally` held in a position foractuation ofthe alarm mechanism by the object within the pocket l, or,more specifically the'purseQ, which ycooperateswith the same to hold byimpingement against the spring member 4 the eXten-` sion 5 projectedinto the vcasing 3. r)The removal ofthe Ipurse 2 from thefpocket willpermit the spring member 4 to quickly move laterally with respectto thecasing into a position 'such as is showny in Fig. 2 such lateralmovement withdrawing the arm 5' ing at their outer ends disks 7 whichare adapted to strike the plate 6 upon rotation of theshaft 8. f

@ne end of the shaft 8 is formed with a beveledgdisk or gear member 9coperating with a corresponding gear member 1() carried by one end of avertically disposed vshaft 11 journaled at each end in spaced partitions12 formed in the casing 3. The opposite end of the shaftll preferablycarries a friction member or roller 13 contacting with a lsimilar,friction member 14 mounted upon a vertically disposed shaft 15 located'adjacent to the shaft 11, as clearly shown in Figs. 1 and 2' of thedrawing. lThe friction roller member 14 is preferably formed with ahollow extension 14 at its lower end which hollow extension is formedwith a plurality of teeth or projections 14 around its inner walls.vUpon the shaft 15 beneath the friction member 14 is loosely mountedanother' friction roller 16 which extends upwardly within the holloviTextension 5 on the spring operating member 4 j which extension normallycontacts with said roller member so as to rotate the same upon rmovementof thel extension outwardly from the casing. Thismovement of theextension 5 therefore imparts rotation tothe member 16 which by reasonof the coperation of the arms 17y with the projections 14'v transmitsmotion to the member 14 and in turn said member rotates Ythe shafts 11la`nd'8 so as to thereby, revolve the hammer member. Said hammer memberinrotatingcontacts With ythe plate or' sound producing member 6 ftherebysounding thel alarm when the object or purse 2 isfremoved vrfromthe pocket to I rihe free extremity ofthe arm, .asshownv in l'figs.'` 1land 2, Ais bent upwardly so asto.

limit the outward movement of said arm by cooperation with theside ofthe vcasing 3.

,InV order that. they purse may be heldin proper position withjrespectto the alarm device comprising my invention the pocket .l lis preferablyprovided with an elastic member 18 secured aroundv one side of thepocket, as shownmost clearly in Fig.y 3 of the drawing.y ln order thatthe pocket may 'be made suitably rigid for laccommodating the structureherein ,sety forth, vone side of the casing 3, designated 19,v may beextended along one side of the pocket as shown in the drawings. f o j'Having thu'sdescribed" the invention what is claimed as new is: i 1. Ina pocket alarm, the combination with a casing adapted to be fitted in apocket, an alarm mechanism in the casing, a spring carried by the casingAand disposed Vexternally thereof within the pocket, fand means adaptedto be actuated by expanding movement of the spring for operating thealarm mechanism, the spring being disposed i for being engaged by anarticle in the pocket for maintaining the spring compressed durment ofthe spring for operatingl the alarm `mechanism, the spring being'disposed for being engaged by an article in the pocket for maintainingthe spring compressed during the presence of the article inthe pocket,

and means engaging the casing and article engaged portions ofthe pocketfor resiliently retaining the article and casing in their given relativepositions.

, 3. ln a' pocket alarm, the combination with a casing adaptedV to befitted in a pocket, an alarm vmechanism* in the. casing, a springcarried by the casing and disposed externally thereof within the pocket,means adapted to' be actuated-by expanding move-- ment of thespring foroperating the alarm mechanism, the spring being ydisposed for beingengaged by an article yin the pocket yfor maintaining the springcompressed during the presence of the article in the pocket, and anelastic band surroundingthe contour ino for maintaining the articleand-casing iny their respective relative positions.

4. In a device of the class described, the combination of a casing, asound plate therein, a rotatable hammer `member adaptedto f impingeagainstsaid plate, a shaft on which iio said hammer member is mounted, aspring actuating member secured. to the outsidey of the casing andhaving an army projecting thereinto, afriction roller disposed in saidcasing and having rolling contact with the arm of the spring actuatingmember, a shaft for transmitting motion to the first mentioned shaft,anda roller member interposed between the lastmentioned shaft and theother vroller member, and clutch means carried by the first mentionedroller Vmember and engaging they second Vmentioned yroller member`wherebyl to ytransmit motion imparted by the arm aforesaid to the.hammer member upon movement of said arm in. one direction and permittingfree movement of extends, the arm being disposed to travel in a path forengaging and actuating the alarm mechanism during longitudinal movementin one direction.
